Question Answered step-by-step An astronaut has just returned to earth after an extended period in… An astronaut has just returned to earth after an extended period in space. Due to the microgravity of space, they have experienced significant atrophy of both their skeletal muscles and their bones. They are currently undergoing extensive physical therapy to regain their lost muscle/bone mass. 1) True/False: The bone loss that the astronaut experienced in space was likely due to the activity of their osteoclasts outpacing the activity of their osteoblasts. 2) True/False: When performing rehab exercises with heavyweights, the astronaut is relying more on fast-twitch muscle fibres which are resistant to fatigue and have more mitochondria than slow-twitch muscle fibres. If you can explain the answers, that would be great thanks.
